On wikipedia it says that the pressure coefficient can be written as
C_p = 1 - (V/V_{inf})^2
where V is the velocity.
So if I have given a steady velocity field, V = (v_x,v_y), does the equation for C_p hold for both coordinates or only the speed \sqrt{v_x^2+v_y^2} ?
I'm supposed to determine the largest and lowest value for C_p and I don´t know which formula to use.
